When we concatenate HackerRank with is the best place to learn and practice codin Given an array of unique characters arr and a string str, Implement a function getShortestUniqueSubstring that finds the smallest substring of str containing all the characters in arr. Complete the following functions in the editor below: The values returned by these functions are printed to stdout by locked stub code in the editor. A simple solution for this problem is to generate all possible substrings of ‘st’ and check if their reverse exist in the ‘str’ linearly.. An efficient solution for this problem is based on the fact that reverse of all substrings of ‘str’ will exist in ‘str’ if and only if the entire string ‘str’ is palindrome.

For example, given the string "figehaeci" and the set of characters {a, e, i}, you should return "aeci". 70% of companies test this subject. Given two strings of length N (P and Q) and an integer S, find the maximum of L such that there exists a pair of indices(i,j) for which we have M(i,j,L) ≤ S. M(i,j,L) refers to the size of the set {0 ≤ x < L | p[i+x] ≠ q[j+x]}. HackerRank Solutions in Python3. C/C++ Logic & Problem Solving i solve so many problem in my past days, programmers can get inspired by my solutions and find a new solution for the same problem. Given an array of integers representing the color of each sock, determine how many pairs of socks with matching colors there are. Saturday, April 29, 2017 . Count of non-empty substrings is n*(n+1)/2. For every character, we consider all substrings starting from it. First calculate how many 'a' are there in the substring. If you start left you could've got a different amount of substring then when you've started on the right – Ismail Jun 4 '18 at 19:45 There is a large pile of socks that must be paired by color for sale.
